MariaDB vs MySQL

Side-by-side comparison, when-to-use-each guide, and instant conversion. Reviewed for 2026.

Quick answer: MariaDB was forked from MySQL in 2009 when Oracle acquired Sun (MySQL's owner). MariaDB is open-source, drop-in compatible with MySQL for most uses. MySQL has more enterprise features (Oracle's commercial editions). For many open-source projects in 2026, MariaDB is a common default, though MySQL remains very widely used.

Frequently asked

?

Can I switch from MySQL to MariaDB?

For most applications, yes — drop-in replacement. Same protocol, same SQL syntax, same drivers. Test in staging first; some newer MySQL features (JSON_TABLE, window function specifics) may differ.

?

Why not just use PostgreSQL?

PostgreSQL is more standards-compliant and has more advanced features (better JSON, window functions, full-text search). MariaDB/MySQL has better replication for simple primary-replica setups. For new projects, PostgreSQL is increasingly the default.
